GoGGLEs.

ASpecicatimi of Letters Patent.

Patented Feb. '7, 1922.

To all whom t may concer/n:

Be it known that I, FREDERICK W. KING, a citizen of the United States, residin at the city of New York, in the county of ew York and State of New York, have invented certain new and useful .Improvements in Goggles, of which the following is a full, clear, and exact description.

My invention has particular application to goggles for use in industrial plants to protect the eyes of the wearer a ainst injury from iying particles and the like. The first consideration with such goggles is the feature of safety, and it is therefore desirable that the eye rims or cups conform to the contour of the features in such a way as to completely enclose the eyes. For industrial goggles of this character metal is the cheapest as well as the strongest andV altogether the most satisfactory material which can be used for the rims, and an object of my invention is to provide a sheet metal construction for such rims or eye cups which will completely enclose and protect the eye, and which will be sufficiently light for comfort and which Will afford the desired ventilation Without impairing the protective quality of the ggles.

In accor ance with my invention I provide sheet metal eye cups of substantial depth and preferably shaped to conform to the features, and provided with ventilating openings for substantially three-quarters of its circumference, the upper inside quadrant being imperforate, and I combine therewith a plvoted foraminous shield member which is adapted to cover the openings 1n the outer half of the cup and screen them from flying particles. The features of the wearer suiiiciently cover the openings in the lower inside quadrant of the cup to shield them from iyng particles, and the eye is thereby completely proteetedv while the openings make the cups suiciently light and afford ample ventilation.

VI shall now describe the illustrated embodiment of my invention and shall thereafter point out my invention in claims.

Figure 1 is a bottom plan of a pair of gogg es embodying my invention;

Fig. 2 is a vertical sectional elevation thereof on line 2-2 of Fig. 1; and

Fig. 3 is an end view thereof.

In the rillust-rated construction the rims for the lenses 1 are Sheet metal .cup members 2 shaped on their inner ed e to conform more or less closely to theV eaturesof the wearer. The eye cups are connected by a suitable flexible bridge member 3 and also preferably by an additional flexible strengthenmg brace 4. The nose piece 4' is disposed between 'the lenses some distance below the bridge member 3, and is attached thereto by 'Patent No. 1,204,161.

To lighten the eye cups and at the same time to provide the desired ventilation, I form several openings 6 in the wall of each eye cup 2, which series of openings extends for about three quarters of the circumference of the cups, the upper inside quadrant being preferably left imperforate for the reason that the features of the wearer would not protect that quadrant.

Foraminous semi-circular shields 7 with a suitable sheet metal binding or edging are pivoted to the eye cups on the central vertical axis of the cups, and are notched at the middle of their bottom edge to receive the end pieces 8 to which the temples 9 are hinged, and thereby permit the shields to occupy a position on the eye cups when the goggles are worn sufficiently far down to cover the openings 6 in the outer half of the cups, the openings being at least partially exposed through the foraminous material,` as appears in Figure 3. The nose and the cheeks of the wearerl will guard the'openings 6 in the lower inside quadrant.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described Within the principle and scope of.

being imperforate, and a semi-circular-shield member pivoted' substantially in the vertical diametral axis of the eye cup and adapted to cover the openings in the outer half thereof.

2. For goggles or the like, a substantially cylindrical eye cup composed of: sheet metal and provided eireumferentially With ventilating openings, the upper inside quadrant cylindrical sheet metal eye cup having the inner portion shaped to conform to the features of the wearer and provided oireurnferentially With Ventilating openings, and a semi-circular shield member of oraminous material pivoted substantially in the vertical diametral axis of the eye cup, and having itsV bottom edge shaped to enablen the foi-aniinous material to cover the openings in lthe outer half thereon 'Y In Witness whereof, I subscribe my signature.
